The cover has a radialslot near its peripheral edge and within theislot is slidably mounted a cutter which has a knife portion and a. handle or-tion with which=the knife may be moved a ong in 2 theslot from a peripheral pocket in the slip cover, -in which the knife 1s inoperative, to a posi'tion in which it pierces the taggers tin. Qmrw binationhas all the well known features; of such combinations. It has been i 2 fionnd-thatcans of this type frequently present asource of danger to the person who opens them and uses them after they have been opened, because the thin annular rim of taggers tin left in the can top is rough and uite likely to inflict a serious scratch or cut. Eisthe object ofour invention to provide a cutter; and a can which will have a smooth inner edge of :the taggers tin which remains after, the circular piece has been removed.
